摘要： An electronic device include: a display, an input unit, at least one processor, and a memory. The input unit includes at least one biometrics sensor and the memory includes instructions. The processor is configured to perform user authentication based on biometric sensing information obtained through the at least one biometrics sensor in response to an input to the input unit. in response to successfully performing the user authentication, the processor is configured to identify whether a duration of the input exceeds a first threshold time. The processor is configured to perform a first function when the duration is less than or equal to the first threshold time The processor is also configured to perform a second function when the duration exceeds the first threshold time.

摘要： A system on chip includes a memory, a main processor that runs an operating system, and first Intellectual Properties (IPs) that perform respective processing operations. The main processor operates to copy target firmware to the memory using a firmware loader, using a hypervisor, block access of the main processor and the first IPs to the target firmware before verification of the target firmware, and using the hypervisor, grant access to the target firmware by a target IP among the first IPs that corresponds to the target firmware after the verification of the target firmware.

摘要： An integrated circuit includes a system memory, a security processor and a non-security processor. An attack against the integrated circuit is made more difficult based on using a key generated by the security processor. The security processor, as an example, reads a program image from the system memory and generates the key based on the program image. In some instances, a dedicated communication channel is provided for communication between the non-security processor and the security processor. The dedicated channel may be used to provide the key to the non-security processor for performance of a security operation.

摘要： A system includes processing circuitry and a system memory configured to store at least one software image. The at least one software image includes at least one program image and a keychain image associated with the at least one software image, the keychain image including at least one soft key. The processing circuitry is configured to obtain a desired soft key associated with the at least one software image from the keychain image based on key information included in the at least one software image, and authenticate the at least one software image based on the obtained soft key.
